TMS570LS0432: SCI interrupt not work normal.

KUANLEI LEE

Part Number: TMS570LS0432
Other Parts Discussed in Thread: BQ76PL455EVM

I am trying to program the TMS57004 Launchpad with the sample code provided by TI to work with the BQ76PL455EVM.

I set the RTI 100ms to update battery data, 100ms polling SCI notification function.

but I just get the first data and when I adjust different voltage my data not update.

I try the debug mod to look WaitRespFrame subroutine,it have run but SCI not update.

Hi Kuanlei,

Is the PL455 waked up? At least 100us pulse is required to wake the PL455 up.

Thanks reply me.

I already solved this issue.

It is the data length problem, it cause the CRC checksum fail.

So it not work normal.
